BIO 123 PROBABILITY AND GENETICS LAB REPORT AND ANSWERS TEST YEAR 2023 1. Based on the parents' genotypes, what is the genotypic ratio expected from a monohybrid cross between the two parents for the trait? The genotype of both parents is Bb. Hence, after monohybrid cross, the genotype ratio can be determined as follows: The F1 generation will have genotype ratio BB:Bb:bb= 1:2:1. B b B BB Bb b Bb bb 2. Based on the genotypic ratio from question 1, what is the expected probability ...

AQA A level Biology topic 7 Latest 2023 Graded A+ What is a dominant allele? Allele which is always expressed in the phenotype even when theres only one copy of it What are recessive alleles? Alleges that only appear in the phenotype if 2 copies are present What are codominant alleles? Alleles that are both expressed in the phenotype because neither one is recessive If an organism carries two copies of the same allele it said to be ........ Homozygous at the locus If an organism carries two ...

Mendel’s First La w: Law of Segregation: each gametes gets one allele for each gene ◆ Allows us to predict outcomes with punnett squares Mendel’s Second La w: Law of Independent Assortment: genes on different chromosomes assort independently of each other ◆ Also applies to more than 2 genes Independent assortment & segregation are both demonstrated during Meiosis I True breeding: homozygous F1 cross ◆ F1 x F1 ◆ Aka monohybrid cross Dihybrid cross: 2 genes crossed ◆ ...
